SELF-OILING SHAFT HANGER.

Application filed July 24,

To all whom it may concern.

Be it known that I, JOSEPH S. Roux, a citizen of the Dominion of Canada, and resid' ing at Manchester, in the county of Hillsborough and State of New Hampshire, have invented certain new and useful Improvements in Self-oiling Shaft Hangers, of which the following is a full, clear, and exact specification.

The object of this invention is the construction of an improved hearing or hanger by means of which a continuous supply of lubricating oil shall be fed to the shafting therein from a reservoir back into which returns all the oil leaking from the shafting.

To this end, I provide the shafting with a wheel rotating in the oil-reservoir and having means whereby the oil brought up by the wheel is taken therefrom and delivered to the upper central portion of the hanger and thence upon the shafting.

In the drawings forming part of this specification, Fig. 1 is a. plan view of a hanger embodying my improvements. Fig.

2 is a transverse section on the line 2-2- in Fig. 1. Fig. 3 is a peripheral view of one of the oil-elevating wheels. Fig. 4 is an under view of the upper section of the hanger. Fig. 5 is a transverse section on the line 55 in Fig. 1.

The reference numeral 1 designates a por tion of a shaft supported in the hanger which is made in two sections, 2 and 3. At each end of the lower section 52 is an oilreservoir i within which is a wheel or disk 5 rotating with the shaft, the two reservoirs being preferably connected by a conduit 6, as shown in Figs. 2 and 5. The upper section 8 is formed with a hood 7 roofing in each oil-reservoir, and having an observation opening 9 closed by a hinged cover 10.

In the section 3 midway of the oil reservoirs is a receptacle 11 having a hinged cover 19., and into which the oil is designed -13 to be delivered as brought up by the wheels 5, the oil therein being adapted by means of holes 18, shown in Figs. 4 and 5, to be conveyed to the upper portion of the surface of the shaft. To deliver the oil from the wheels 5 to the receptacle 11 a tangential 1923. Serial N0. 653,486.

tubular scraper 1% is provided for each wheel. The latter being peripherally grooved, as at 15 in Fig. 8, each scraper is provided with a projection 16 fitting in this groove, and projections 17 at the sides of the wheel. film of oil brought up thereby will be received in the tubular scraper and will flow therefrom through the tubes 19 into the receptacle. In case more oil is delivered to the reservoir than can be discharged to the shaft, overflows 20 are provided, as shown in Figs. 1, and 5, connecting with tubular conduits 21 emptying into the reservoirs, as indicated in Fig. at.

As illustrated in Fig. 2, each wheel 5 is provided with a scraper 22 adjusted by a set screw 23, by means of which to regulate the amount of oil brought up by the wheels.

In addition to this adjustment, the tubular scrapers 14s are tangentially movable by means of screws 24, both to ensure the re ceipt of the oil from the wheels and to take up wear.

What I claim is:

1. A self oiling hanger comprising an oil reservoir below the shaft for which the hanger is designed, a wheel turning with said shaft and dipping into the oil in said reservoir, a tubular scraper slida-bly supported tangential to the upper periphery of said wheel, a pipe receiving the free end of said scraper, a lug rising from said scraper, and a screw for adjusting said lug and scraper.

2. A self oiling hanger comprising an oil reservoir below the shaft for which the hanger is designed, a wheel turning with said shaft and dipping into the oil in said reservoir, said wheel having an annular groove in its periphery, and a tubular scraper tangentially disposed with respect to said wheel, the engaging end of said scraper having a tongue fitting in said groove and other projections contacting with the flat faces of said wheel.

In testimony that I claim the foregoing invention I have hereunto set my hand this 17th day of July, 1923.
